na'eccosf f '1 To all whom it may concern Be it known that I, FRANK L. MOORE, a

citizen of the United States, residing at Trumansburg, in'the county of Tompkins. vState of New York, have invented certain new and useful Improvements in Couplings for Automobile-Radiators and the like, of which-the following is a specification, reference being had therein ing drawing.

" My invention relates to couplings for water pipes and the like, with particular reference to the couplings used on the water jacket connections of automobile engines.

In all water-cooledgas engines employing radiators the intake and discharge pipes of the radiator are connected to discharge and intake pipes respectively of the water jacket of the engine, a pump being interposed to maintain a circulation. The maintenance of tight oints or couplings between the water jacket and the radiator terminals is not as simple in automobile engines as it would be with stationary pleces of apparatus and the time consumed in making repairs and put ting in new couplings becomes of importance because of the loss of efliciency in any traveling imit caused by stoppage.

A common method of making such connections is by using short section of rubber and canvas hose wired or otherwise secured at both ends to short lengths of pipe protruding from the engine jacket and the radiator respectively. INhile it is a comparatively easy matter to remove such an old and worn out radiator hose, or one which has become defective, by loosening the clamps or'wires and .cutting the hose lengthwise with a knife, to replace it with a new one is sometimes a more difficult problem, and in my experience in many cases it has been absolutely necessary to remove the radiator in order to replace the lowest or discharge connection therefrom. The problem is complicated by a variety of pump connections, especially if the same happen to be in-, terposed'in constricted space between the radiator and the engine.

My invention is intended to solve this problem by combining both the hose and the clamp in a single unit, which mustbe water- I tight when in place, adjustable to various diameters of hose connections, constructed in various lengths, and easily applied or removed without disturbing the radiatorfrom its permanent position.

V l Briefly stated, the invention consistsbf two essential parts, vizl, apair of rubber rings to fit over the ends of the pipes to bei coupledjtogether, and a metal band spansizes and .the metal clamping strip with'suf ficient overlap for allsizes', these parts may be fitted to various diameters of pipe, and gl by reason of the resiliency'f'of the rubber. rings slight variations in standard sizes-are unimportant=- By making the metal strips" indifferent widths, the length of the icoua ard rings; 1

My invention is illustrated in the accom-- panyingdrawings in which F igure 1 1s a perspective view with parts pling-. 'can be altered, using the same stand-'7' broken away to show a portion ofthecou-fi pnng in section,

coupling applied to the waterjacket connections, omitting the pump for the sake of clearness and simplicity of illustration Referring first to Fig. 3, E is the. engine I is the discharge pipe from the engine water jacket, coupled to the intake pipe for the radiator. O is the intake pipe for the water jacket, coupled to the discharge pipe from the radiator. 0,0,

C, C, are couplings embodying my invention.

Referring to Fig. 1, II' are'respectively coupling is used, consisting of the two rubs ber rings or gaskets G-''G', shaped as shown with shoulders or flanges butting against the ends of the pipes respectively, so that the joint cannot work apart. Surrounding these v two rings and lying in adjoining rabbets in their circumferential surfaces, isa clamping strip shown attached in Fig.2. Referring to that figure, 13 is a long metal band carry ing a tongue T extending from the middle j of one end, and having a tubular socket '1 attached to the other end: This socket tube is cut away-at 7 (see Fig. 1 to receivetheend of the tongue T when the bandis in place inthe coupling. Fitted within the socket tube is a split tube 2, long enough to protrude from the socket at both ends and provided with spanner openings at for turn ing it.

' Fig. 1, after which the tube 2 is locked in the socket -1 by suitable means which I have shown as set screws 5, themselves provided with alocking wire 6 to prevent their loosening underroad vibration or other causes.

'- y The jointin Fig. 1 isa short one, as the rubber rings abut; but it will be evident Without additional illustration that by making the band B of greater width, the ring;

(Sr-S can be separated, and the band "engagethem by its two edges only, leaving its middle portion between the rings exposed to the water and forming part of the coupling. Thus, by providing bands with their integral socket tubes and key tubes, of varigous widths, say irom two to six inches, and

by providing .rubber rings GG of differ ent sizes, I can quickly and easily couple together the ends of the pipes I-I', or 0-0 as the case may be in widely varying types and makes of automobiles.

hat I claim is':-

A coupling for water pipes and the like, particularly a coupling for automobile radiator connections comprising a pair of rings of water-proof resilient material adapted to fit over the ends of the pipes to be coupled, and shaped so as to prevent longitudinal displacement on the pipes, in'combination With a combined coupling and clamping,

band of metal carrying a-tongue extending from an intermediate portion of its length to'one end, and a receiving and clamping so fitted and arranged that the band may be overlapped, drawn taut under a compression strain, and looked around the rubber rings.

In testimony whereof I ali ix my signature.
